Background: A third-generation microwave-based device has been developed to treat axillary hyperhidrosis by selectively heating the interface between the skin and underlying fat where the sweat glands reside.
Materials And Methods: Thirty-one (31) adults with primary axillary hyperhidrosis were enrolled. All subjects had one to three procedure sessions over a 6-month period to treat both axillae fully.
Background: Duration of effect and effectiveness limit current options for treating axillary hyperhidrosis. A new microwave procedure for treatment of axillary hyperhidrosis has been tested.
Study Design/materials And Methods: Adults with primary axillary hyperhidrosis were enrolled in a randomized, sham-controlled, blinded study.
Background And Objectives: Hyperhidrosis is a condition that affects a large percentage of the population and has a significant impact on peoples' lives. This report presents a technical overview of a new noninvasive, microwave-based device for creating thermolysis of sweat glands. The fundamental principles of operation of the device are presented, as well as the design and optimization of the device to target the region where the sweat glands reside.

Materials And Methods: Three institutions contributed consecutive cases in which a mammogram was obtained to evaluate a clinical finding, after which a histologic diagnosis of breast cancer was made. Clinical data and the mammograms were reviewed to determine the nature of the clinical findings and to document the location and characteristics of 212 biopsy-proven cancers in 197 patients who met the study criteria.
Purpose: To evaluate, by using a computer-aided detection (CAD) program, the nonspecific findings on normal screening mammograms obtained in women in whom breast cancer was later detected at follow-up screening mammography.
Materials And Methods: Four hundred ninety-three mammogram pairs-an initial negative screening mammogram and a subsequently obtained screening mammogram showing cancer-were collected. The mean interval between examinations was 14.
Purpose: To retrospectively review nonspecific findings on prior screening mammograms to determine what features were most often deemed normal or benign despite the development of breast cancer in the same location detected at follow-up screening.
Materials And Methods: Four hundred ninety-three pairs of consecutive mammographic findings were collected from 13 institutions, consisting of initial normal screening findings and a subsequent finding of cancer at screening (mean interval between examinations, 14.6 months).
Purpose: To characterize the mammographic appearance of invasive lobular carcinoma in a large series of screening-detected consecutive breast cancers and to evaluate the ability of a computer-aided detection system to mark these carcinomas.
Materials And Methods: Investigators used the Breast Imaging Reporting and Data System lexicon to characterize lesions as part of a retrospective review of 90 screening mammographic examinations that led to biopsy-proved diagnosis of 94 invasive lobular carcinoma lesions. The 40 available prior mammographic examinations (obtained 9-24 months earlier) were also reviewed to characterize any visible findings.
